Production that can be put on each phase
Production by development of process control or process control support system
Functional evaluation
Function evaluation support system development
Situation needs of severe design development staff
Background
It proposes a certain technological solution early.
Processing technology securing to be made embodiment
Big change in design milieu and development demand needs
The design development
worker's reduction
Shortening at development period
until releasing new product
Many varieties development of a small amount
New rival entry from another field Rapid exchange fluctuation
Power & speedup is promoted by introduction of TRIZ & Goldfire Aim
Theme decision
Arrangement/classification of ideas
Selection of concept
Function-attribute analysis Cause-effect analysis
Idea generation using Inventive Principles
Idea generation using Evolution Patterns
Uniting of ideas of each subsystem
Generation of concept of main system
Absolute grading of the final system concept
Making of problem essence
(extraction of primary cause)
Idea generation using TRIZ
Idea Making to effective
(selection and connection)
System Absolute grading
Main problem extraction
Technical contradiction definition
Knowledge retrieval Idea generation
The final output: Image chart of concept
Physical Contradiction, SLP, Ideal Final Result, etc. are used
according to the situation.
Device analysis Root cause analysis
System Retrieval from target function
System Retrieval from pivotal question
Problem 1: Box sealing mechanism for illegal prevention
Sealing mechanism of internal basic case with game device
Purpose of management of unlawful computer
access prevention of the main base
Signs opened when the unlawful access person opens the case should remain
Mechanism of sealing
Work of threaded portion
It locks to the screw
Electric lock
Setting signal of opening
The screw is increased
Sensing measures
Secret gas enclosing
The threaded portion is covered
Dissolution of lock
medicine Because the gas comes off when opened, it gets
known that it was opened
Measures are exaggerated
The cost is high
Conception from Preliminary Action principle ・Part or all of a necessary change are done to the object beforehand ・The object is prepared beforehand to accomplish operation from the most convenient place, and useless time is prevented being taken to accomplish operation
Easy God match mechanism
God match
Conception from Preliminary Anti-action principle ・When it is necessary to accomplish operation that brings an useful effect and a harmful influence at the same time, it is necessary to be going to replace this operation with the anti-action later, and to control the malignant influence ・The stress is generated in the object beforehand, and it opposes the unnecessary operation stress to be generated back
Driver insertion
Open mouth
Lock It locks when insertion of the driver is tried
and the opening is opened
The work that the unlawful access person opens by nondestructive is
difficult
The mechanism of the lock is made a Black Box
Conception from the Self-service principle ・Supplementary support functions are accomplished and the object does self-service ・The abandonment resource, the abandonment energy, and the waste quality are used
The unlawful access person is made to recognize sealing with
the screw
The stick to recognize the dummy screw doesn't turn in the opposite direction though it turns in the direction of a positive
rotation of the screw tightening by spring in the housing.
Only the screw head is seen from the unlawful access person and the internal mechanism is not understood.
Therefore, when the screw runs idle, it misunderstands it.
Problem 2: Missing page prevention in large-scale delivery system of books
Book sales commission company
↓ Each bookstore
In the book sales companies, the book that there is an
order for each bookstore is sorted and it sends it out.
It loads it into the delivery car by finally handling the
shooter.
Missing page
Ⓐ Impact at passing the final shooter Ⓑ Fall when system of book is passed Ⓒ Hanging book damage of the taking out mechanism Ⓓ Transcript of dirt such as oil and drops of water
Idea A: It changes it into the method that abolishes the shooter, changes into the elevator type or accompanies it. Idea B: The angle of the shooter is made gradual. Idea C: The system speed is slowed down.
・Large scale equipment remodeling and restructuring ・Synchronization between systems and the control is not revokable
Improvement ideas
・・・70%
…
Cause of missing a page of a book
Rolling control shutter
Energy-absorbing damper
Rolling control convex shape
Simple remediation measure by TRIZ ・From a lot of directions where the hint is obtained from TRIZ It comes off new awareness multilaterally based on the peculiar technology that we have and it obtains it easily moreover without omission.
Effect and view
Effect In the business step from the idea putting out to make for trial purposes-DR-mass production ・Mechanism making for quantification of qualitative product. ・Proof of output of conception (Oppositely, it is possible to reconfirm directionality of conception from the experience in TRIZ view)
Our working environment ・Small-scale organization body (An organization body that is called TRIZ team does not exist)
View In the small and medium-sized enterprise like our company that will advance the development support that the customer requests in the future, I am convinced that the introduction of TRIZ leads to the flowering of a big possibility.
